Compressive imaging Single Pixel Camera (SPC) [1]} is a classic example of compressive imaging. It uses a programmable digital micro-mirror device (DMD) array to multiplex the scene on to a single photodetector. Using different settings on the DMD, we can sequentially acquire a set of measurements. Thus, scene at full resolution is reconstructed from much less than 100% measurements. Compressive imaging systems pose a viable solution for high resolution imaging in non-visible parts of the spectrum where full frame sensors are very expensive.
